Detailed explanation-1: -The upper chambers-the right and left atria-receive incoming blood. The lower chambers-the right and left ventricles-pump blood out of your heart.
Detailed explanation-2: -Your upper chambers are called your right atrium and left atrium. Your lower chambers are called your right ventricle and left ventricle. Your chambers work together to manage your heartbeat.
Detailed explanation-3: -The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides. On the right side of the heart, the right atrium and ventricle work to pump oxygen-poor blood to the lungs.
Detailed explanation-4: -There are two atria in the human heart – the left atrium receives blood from the pulmonary circulation, and the right atrium receives blood from the venae cavae of the systemic circulation.
